[Hallicrafters] Hallicrafter's TW-1000A Portable Eight Band Receiver

[Gerry Steffens]

Note that the bandswitch has nine positions and 8 bands.  There is a
position between the BC band and the long-wave band position which shows =
the
yellow flags in all bands but receives nothing.  The ninth position is =
the
long-wave position and has a single yellow flag in the LW window.  If =
you
have the radios in the interim position you will hear nothing.  If you =
are
in the correct LW position you should hear noise and possibly hash from
remaining aircraft beacons (I hear a couple here in Minnesota).  I have =
the
literature for the TW-1000 and more but no explanation of the position
between BC & LW.

I know nothing of the numbers manufactured but I have three TW-1000 and =
only
one TW-600, TW-1000A and TW-2000.  From what I have observed the most =
common
is the TW-1000 followed by the TW-500 & 600 (same radio, different =
color)
and then the TW-1000A & TW-2000.=20

Receiver

I purchased a Hallicrafter=92s TW-1000A at the Socorro,
New Mexico Hamfest (about 100 South of Albuquerque on
I-25) from Robert W6RQR for $75.00 during late
October, 2005. I found out later that the TW-1000A had
the AM loopstick antenna mounted above the chassis
which this one did. The TW-1000 had the AM loopstick
antenna built into the front cover. Physically, the
exterior is in good condition. Upon opening the back
panel I found the interior including radio chassis to
be in near new condition. The built in telescoping
antenna is intact and unbent. It also has the original
Skyrider loopstick external antenna for AM and LW
reception.  Initially, it did not receive on any
bands. After replacing the 1U5(Detector), which had an
open circuit pentode section, it still did not receive
on any bands. During an annual antique radio clinic, a
member of our New Mexico Radio Collector=92s Club; Chuck
Burch one of our members worked on it. After working
the bandswitch many times, the years of oxidation
began breaking up on the switch contacts. Finally the
AM broadcast band began receiving quite well. I used
two applications of WD-40 on the bandswitch at home.
It then began receiving well on all bands.

I have researched this receiver and found there are
three models manufactured from 1952 until 1956,
TW-1000, 1000A and 2000. I did purchase an excellent
reprint of the original service instruction manual on
E-Bay.  However I have several questions:

1) When I set it to the AM broadcast band and change
bands to the last position I receive nothing? I am
assuming this is because I have switch to the LW or
old =20
Loran navigational band from 180 through 400 Kcs and
there is nothing in New Mexico to receive?
2) This receiver was in direct competition with the
Zenith Trans-Oceanic as were many other manufacturers
such as GE, Philco, Stromberg Carlson and RCA. Was
this model low production with Hallicrafter=92s? If so
are there any documented records as to how many of the
TW-1000/1000A/2000=92s were manufactured?


Thanks!
